Answer:
The wavelength will be 4 cm, frequency will be 4.66 Hz and wave speed is 18.6 cm/sec
Explanation:
Given:
No. of crest = 13
No. of trough = 15
Time = 3 seconds
Hence, 1 crest or 1 trough = 
therefore,
13 C + 15 T = 
=
Time given 3 seconds
= 
2 cm distance is travelled is time period
Again wave will travel in 1 T = 4 cm
wave speed v =
= 
= 18.6 cm/s
Answer: Acceleration
Detailed Explanation:
Acceleration is defined as the rate of change of velocity.
Answer:
